The Giulia Quadrifoglio beats both the BMW M3 and Mercedes-AMG C63 in one critical category: driving soul - and for Nassau County enthusiasts who live on I-495 and Meadowbrook Parkway, that difference matters every single day.
Bottom Line: The Giulia Quadrifoglio delivers the most emotionally engaging performance sedan experience in this class, while the BMW M3 offers the sharpest precision and the AMG C63 S leads in daily luxury.
- Giulia QV: 505 HP Ferrari-derived V6, best steering feel, starts ~$83K
- BMW M3: 503 HP straight-six, fastest 0-60 at 3.4s (Competition), starts ~$78K
- AMG C63 S: 671 HP PHEV four-cylinder, most daily luxury, starts ~$86K+
Power and Performance: Three Very Different Answers
The complete Giulia Quadrifoglio guide covers the QV’s full story, but the raw numbers here tell you something important. All three cars are genuinely fast - the real differences emerge in how they deliver that speed.
The Giulia QV’s 2.9L twin-turbo V6 was co-developed with Ferrari and produces 505 HP at 6,500 RPM with a 443 lb-ft torque peak. The engine revs freely, sounds extraordinary through the optional Ti exhaust, and pulls hard from 2,000 RPM all the way to redline.
The BMW M3 Competition uses BMW’s own S58 straight-six making 503 HP. It posts the quickest 0-60 in this group at 3.4 seconds with launch control - a number the QV matches more with character than raw timing-light advantage.
Mercedes completely reinvented the C63 S for the current generation, replacing the beloved V8 with a 2.0L four-cylinder PHEV system producing 671 HP combined. It’s brutally quick in a straight line but generates controversy among enthusiasts who miss the old engine’s personality.

Daily Driving on Long Island Roads
Nassau County roads present a specific challenge for performance sedans. The I-495 Long Island Expressway offers stretches where these cars can breathe, but local roads through Westbury, Jericho, and Garden City include enough pavement imperfections to test any sport suspension.
The BMW M3 is the most versatile daily driver of the three. Its adaptive suspension manages LI’s mixed road surfaces well, the interior technology is intuitive, and the driving position suits long commutes without fatigue.
The Giulia QV is genuinely livable in its Natural DNA mode. Ride quality softens meaningfully compared to Race mode, trunk space at 11.6 cubic feet handles grocery runs, and the cabin - while not as tech-heavy as the BMW - has a focused, driver-centric feel that many owners prefer.
The AMG C63 S leans hardest into luxury. Its PHEV system provides an electric-only commute range of around 12 miles, which can be useful on shorter Nassau County errands. The downside: the electric motor adds significant weight to what was once a nimble car.
"Customers who come in expecting just a fast sedan leave genuinely surprised by the Quadrifoglio. It's not just quick - the steering, the soundtrack, the way it responds - Nassau County drivers who commute the I-495 corridor tell me it makes every drive feel like an event, not a chore."

Service Costs and Long Island Ownership
Ownership costs vary significantly across these three cars, and Nassau County buyers should factor in local dealer proximity when choosing. Westbury Alfa Romeo serves the entire region including Roslyn and Jericho, providing convenient access for QV service appointments.
The Giulia QV carries Alfa Romeo’s 4-year/50,000-mile bumper-to-bumper warranty. Routine oil service runs approximately $150-200 per visit using the required synthetic oil. Brake pad replacement - expect it more frequently given the Brembo setup and enthusiastic driving - runs $400-600 per axle.
BMW’s service intervals are slightly longer, and its warranty (4 years/50K) is comparable. The M3’s brake wear can be equally aggressive. AMG service tends to be the most expensive of the three - C63 S oil changes often exceed $200, and the PHEV battery system adds a new maintenance category that long-term reliability data is still establishing.
For buyers weighing depreciation: all three cars depreciate heavily. The QV’s Italian heritage and emotional appeal have built a loyal enthusiast following that helps support used values, though the BMW M3 historically holds value better at the three-year mark.
Track Performance: Which Car Wins at the Limit?
Nassau County driving enthusiasts occasionally take their cars to track days - events at nearby venues give these cars a chance to show what they can really do. On a proper circuit, the results shift compared to street driving.
The Giulia QV’s Torque Vectoring Differential is the hardware story here. It actively distributes torque between the rear wheels, enabling rotation on corner exit that is deeply intuitive and adjustable with throttle. Few cars at any price deliver this level of driver engagement.
The BMW M3 Competition is arguably the more complete track tool for regular drivers. Its balance is more neutral, setup is easier to predict, and the M xDrive AWD version adds wet-weather confidence for those occasional rainy track days.
The AMG C63 S suffers at the limit from its weight gain - the PHEV system adds roughly 400 pounds versus the old car. It remains fast, but the chassis no longer communicates with the driver the way the previous C63 did. Enthusiasts have noticed.
Check NHTSA vehicle ratings for the latest safety data on all three models, and review NHTSA recalls before purchasing any used example from this generation.
Driving Character: The Deciding Factor
Spec sheets don’t capture why buyers choose between these cars. The real differentiator is character - the subjective, emotional connection a car creates over thousands of miles of Long Island commutes and weekend drives.
The Giulia QV sounds unlike anything else in this class. The Ferrari-derived V6 produces a mechanical wail through the exhaust that the BMW’s straight-six and the AMG’s four-cylinder simply cannot replicate. For buyers who want their car to make an impression at every on-ramp, nothing here competes.
The BMW M3 rewards precision and technical skill. It’s the car a driver improves with - every input has clear, direct feedback, and the chassis communicates exactly where the limits are. Jericho and Garden City commuters who value control over drama often prefer it.
The AMG C63 S remains an excellent luxury sport sedan, but the character shift from the V8 era has divided its buyer base. If daily comfort is paramount and performance is secondary, it earns consideration. If driving soul is the priority, the other two leave it behind.

Frequently Asked Questions
Is the Giulia Quadrifoglio faster than the BMW M3?
The BMW M3 Competition posts a slightly quicker 0-60 time at 3.4 seconds versus the QV’s 3.8 seconds. However, around a circuit and in real-world driving feel, many drivers consider the Giulia QV the more engaging and rewarding car despite the small timing difference.
How does the AMG C63 compare to the Giulia QV now that it uses a four-cylinder?
The current AMG C63 S uses a hybrid 2.0L four-cylinder making 671 HP combined - which is more power on paper but a fundamentally different driving experience. Many performance enthusiasts feel the QV’s naturally-building V6 character is more satisfying than the C63’s electric torque fill.
Which performance sedan is best for daily Long Island commuting?
The BMW M3 is the most versatile daily driver for Long Island roads. The Giulia QV is close behind and offers far more character. The AMG C63 S prioritizes luxury comfort but carries more weight than the previous generation.
Where can Nassau County buyers test drive all three?
Westbury Alfa Romeo serves the Nassau County region including Jericho, Garden City, and Roslyn. Schedule a test drive to experience the Giulia QV firsthand - the difference in character is immediately apparent from behind the wheel.
Does the Giulia Quadrifoglio hold its value compared to the M3?
The BMW M3 has historically held its value slightly better at three years. However, the Giulia QV’s limited production and Ferrari engine connection have created a strong enthusiast following that supports used values - particularly for low-mileage, well-maintained examples from Nassau County and the greater Long Island market.
